FLUID-IPBESSUM] PUMPING APPARATUS.

Tc c-ZZ whom it may concern:

Be it hnown that we, Lnwls C. BAYLES, a citizen of the United Lit-ates, and a resident of Easton, county of Northampton, and

a State of Pennsylvania, and HERBERT T. ABRAMS, a citizen oi the United States, and a resident of @renge, county of Essex, and State of New Jersey, have invented a certain "fluid-Pressure Pumping Ap aratus, 6f

for instance. Because of the great depth,

two-thousand feet or more for instance, and

the comparatively small amount of oil which is available for recovery, at anyone time,

A l reciprocating pump is expensive and imprccticable. When a certain amount of oil i covered, the pump must be stopped until ncnt oil has flowed into the Well again enable the pump to be used and this may 2 mire considerable time. I

Furthermore, pumping apparatus of varir'. kinds located in the bottom of the well i ving valves forming component parts the pump, are unsatisfactory because the d with mud or other foreign matter.

object of the present invention is to encble the liquid in a nearly exhausted well to be readily end economically recovered by which is simple and cheap to construct, and is vulveless in so far as the parts at the but him of the well are concerned.

Another object of the invention is to enable such a well. to be automatically discharged by fluid pressure from time to time when the liquid has risen in the well to a iver Ent. After each discharge the main .rlnid pressuresupply is stopped or cut oil and is used again until the proper amount liquid has flowed. into the well The appnrstus not require watching s are apt to pt out of order or become means of fluid pressure um in a aratus or hand control but is entirely automatic and dependent for operation on the back pressure created in a casing forming a pump chamber adapted to be located near the bottom of the well. v

The apparatus is shown in one of its proferrcd forms in the accompanying drawing, in which,

Figure 1 is a diagrammatic longitudinal sectional elevation, broken in its length", of a deep well having our apparatus applied thereto, v

Figure 2 is an enlarged sectional elevation of the controlling valve in closed position,

Figure 3is a similar View of the valve in open position, and

Figure 4 is a similar view with thevalve closed, but certain parts in a different position from those indicatedin Figure 3.

Referring to the drawings, the deep well A which may be an oil well, is assumed to be greatly depleted ornearly exhausted of its oil and for the purpose of recovering this oil, a casing B forming a punip chamber is adapted to be located in the well near the bottom of the well and below the level C of the liquid to which the oil will rise in the well, after a given period of time.

The casing B is preferably provided with the upper head D and the lower head E, and a filling pipe F as shown extends from a point G within the pump chamber near the upper headD, down through the lower head E to a. point H near the bottom of the well.

A discharge pipe J extends from a point K within the pump chamber near the bottom head E, through the upper head D to the surface of the ground L and is preferably provided with adown turned end O discharging into a tank or hopper P. This discharge pipe J is preferably provided with a. vent Q, within the pump chamber near the upper-head I), through which pressure fluid as compressed air, entering the pump chamber may escape to atmosphere until the vent Q, is closed by the liquid rising in the ump 0 chamber from the well through the filling pipe F.

A main fluid pressure supply pipe R ex-. tends from the surface of the ground to the pump chamber and terminates substantially at the point S above the height of the upper end G of the filling pipe. As the liquid in the well rises through the filling pipe F and fills the pump chambenthe air above the liquid will escape through the vent Q, until said vent Q is-closed by the liquid. The back pressure then created in the supply pipe R is utilized to control the opening of the controlling means T' connectedto the supply pipe above groundfand automatically supply fluid under line pressure from the supply line U to the pump chamber to discharge the liquid. This controlling means T preferably in the form of a valve, includes means for continuously permitting leakage of pressure fluid down the supply pipe R to the pump chamber untildischarge takes place, and in this instance, means are provided con-v trolled by the liquid discharged for cutting oil the main pressure fluid supply from the main line U tt the pump chamber, so that the apparatus is in readiness to permit the filling of the pump chamber again with oil or other liquid, and. the well will be intermittently and automatically discharged.

The controlling apparatus indicated by the character T comprises a valve casing V to which the main supply line U is connected and to which the supply pipe R is also connected. A main valve l V is located in the casing V having the head X controllingthe passage of fluid from the main line U to the supply pipe R. The main valve W is preferably spring pressed and is normally held in closed position, as indicated in Figure 2; by means of the spring Y underneath the adjustable cap Z having the vent (1.. v The main valve \V is preferably controlled by the auxiliary valve 6 shown in the form r of a cylindrical pin, in the end of the valve casing V and provided'with a groove 0 controlling commnnication between the by-pass and-the head 6 of the main valve. auxiliary valve is also provided with a passage f extending from one end of the valve g to an opening [1, at the side'of the other end of the valve, so that as the auxiliary valve is moved up and down, the space beneath the head 6 of the main valve \V may be vented to atmosphere.

In this instance a lever is pivoted at the point is to the valve casing V and is also pivotally connected at the point 0 to the auxiliary valve 6. A retracting spring 7) normally holds the lever y' retracted against the valve casing V, as shown in Figure 2, and a bucket g or-( tlie1"suitable receptacle is hung from the outer end 1' of the lever, and located in a position adjacent to the upper end of the discharge pipe J so that some of the liquid discharged will pass into the bucket through the small pipe s and when shiii'cient liquid has weighted thebucket. the tension otvthe spring p will be overcome and tire lever 7' flill assume the position ini v ,du-atcd in F gure "l. A stop in the .un-m of The i a hook it is preferably provided on the la."

to limit its movement.

We are not to be understood as limiting the invention to the particular form oi con-- trolling valve illustrated in the draw-i a suitable valve and mechanism shown for the purpose of the invention and other equivalent controlling devices could, be con structed by those skilled in the art without departing from the spirit of our invention In this instance, the controlling valve mechanism is so constructed that co 'tllii leakage of air under pressurc is pe .on the mainline U down through the sup; pipe R to the pump chamber.

lo acz plish this object, the valve VJ purpr made a loose lit in the alve' casing that there will always be leakage pa head X to the pipe R and alsopast the head 6 through the bypass d to the pipe it when the valve is in the position indicated in Fig ure 2. This constant leakage of air or pressure fluid passes to atmosphere thix'iugh the vent hole Q in the discharge pipe al until said hole is closed.

In the operation of the apparatus, the oil entering the well will rise in the filling pipe F and pass into the pump chamber in which the level will rise until the vent Q; is closed. If it be assumed that the pump casing B is located a given distance below the level oi the liquid to which the oil will rise in the well, back pressure will be created in the supply pipe It due to the height of the liquid in the well above the vent Q, aug mented by the leakage referred to and the parts of the controlling mechanism are so adjusted that this back pressure will be suiticient, when acting upon the head c of the main valve llhtowhich the pressure is cone municated through the bypass (I, to raise the main valve lV againstthe spring "r to the position indicated in Figure 3. Pressure fluid from the main line l' will then llU ad mitted to the pump chamber and the oil within the pump chamber will be discharged up through the discharge pipe .I to the sur face of the ground thus emptying the chamber.

The function oi the bucket or receptacle 9. is to pulldow'n the controlling lever 15 "when suilieint oil has entered the lmcket and inove the love; to the position lllllllfilldll in Figure l, 111 whi' .li case the space under the head (2 of the main valve W will be rented to atmosphere through the passage f and the spring Y will close the main valve and shut oh. the pressure fluid supply to the pump chamber. An aperture u is provided in the bottom of the bucket o to permit lhe oil in leak out and when sullicienl oil has leaked from the bucket, the spring 1/ will restore the li\l to its initial position as indicat d in Figure 3 so that the controlling na chanism is ready for automatit operation when insect e p the pump chamber has again filled with oil;
